| 摘 要： | 经过试验,用高稳系数法分析品种的高产稳定性,计算简便且分析容易,但比较粗放。回归系数座标分析法较为详细准确,缺点是比较繁琐。所以在对区试结果不需详细分析时,用高稳系数法较简便容易;如需详细分析时,则用回归系数座标分析法较准确可靠。同时对几种品种稳定性参数的准确性进行了比较分析,结果表明品种间回归系数的大小能较准确地反映出品种间稳定性差异程度的大小,其对稳定性的代表性要准确于其他稳定性参数。

| Abstract: | Analysis results showed that stability parameter and the high stable yield coefficient (SPHSYC) is easier but rougher,while coordinate analysis of regression coefficient (CARC) is more accurate and detailed.It is suggested to use SPHSYC for a coarse analysis of regional trial result and to use CARC for a detailed one .Accuracy of a few stability parameters for varieties was also compared and analyzed,which showed that the difference of regression coefficient of the varieties accurately displayed the difference of their stableness. |
